NEWARK - The teenager teared up as she testified Wednesday that she thought if she went along with what Roger Black wanted, he would let her go.

She described being shown a silver knife multiple times and feeling "disgusted" as Black, 31, performed sexual acts with her.

The teen had met Black on Oct. 16 as she was walking down East Main Street. Black had pulled over and offered her a ride, and after some persistence on Black's part, the teen said she got in the vehicle.

After driving a few minutes, the teen testified Black showed her a knife and told her to do what he said. Black then drove to the parking lot of Ben Franklin Elementary School and performed a sex act, she said.

Black then drove his vehicle to a different location in the southern part of the county and pulled over in lot near a truck stop. The teen testified Black ordered her to take off more of her clothing and climb on top of him in the driver's seat of the vehicle.

When she refused, Black got on top of the teen in the passenger seat and performed a sex act.

The teen said after driving around for hours "for no reason" in the Columbus area, Black dropped her off at an area in Newark and told her to walk forward and not look back.

After calling police, a sexual assault kit was taken at Licking Memorial Hospital. A forensic scientist from the Ohio Bureau of Criminal Investigation testified Wednesday that trace amounts of semen were located on the alleged victim's jeans, which were collected during the sexual assault examination.

The teen identified Black in a photographic lineup about five days after she said the assault took place.

Black's attorney, Kort Gatterdam, questioned the teen about inconsistencies with her statements to police during his cross-examination. The teen said she had trouble remembering some details.

When asked about her issues with recalling some information by Assistant Licking County Prosecutor Chris Reamer, the victim said she "didn't want to remember ... because I didn't want it to happen."

Black's trial is expected to continue Thursday. He is charged with two counts of kidnapping and three counts of rape, all first-degree felonies.
